Chrome supports bookmarks whose URIs are not URI-encoded, such as "javascript:" and "data:" (e.g. "javascript:alert('hello');"). Firefox automatically encodes them when adding a new bookmark.

EverSync loses the URI and replaces it with "incorrecturl". It can also overwrite working bookmarks. I'm sure most of your users have never experianced it but for programmers this is EXTREMLY annoying. It also affects non-technical users that use such bookmarks to open the current page in Google Translate or compares an Amazon products to similer results in eBay.
